The older version of the PPTX file is PPT, which was used in Microsoft PowerPoint 97 through 2003. Note: Microsoft PowerPoint's PPSX format is similar to PPTX except that it will open directly to the presentation while PPTX files open to the editor mode.
Atherosclerosis is a disease in which plaque builds up inside your arteries. Arteries are blood vessels that carry oxygen-rich blood to your heart and other parts of your body. Plaque is made up of fat, cholesterol, calcium, and other substances found in the blood. Over time, plaque hardens and narrows your arteries.
Background. Atherosclerosis is a degenerative disease of the arteries resulting in plaques consisting of necrotic cells, lipids, and cholesterol crystals (see the images below). These plaques can result in symptoms by causing stenosis, embolizing, and thrombosing. Atherosclerosis is a diffuse process with a predilection for certain arteries. This article describes the history and impact of this process as it occurs in the extracranial carotid artery. Carotid plaque.
